What if your spouse doesn’t get along with the rest of your family?

My brothers wife is kinda whiney Ann's my father is kind of abrasive but funny unless you take it to personal and they pretty much have had no relationship with my father and his 2nd wife and three half brothers since they married 35 years ago. She makes fun of my half brothers whom i love and my father r.i.p. and step mom. Nothing was sacred to dad and the joke was coming if he though it was funny.
